PROCEDURE TO USE / APPLY SG 460 SYNTHETIC HI – TEMPERATURE BEARING GREASE .
- It is recommended that the bearing should be 100 % clean to use synthetic grease. However , 10-15 % contamination of petroleum based grease in it is permissible . – when it is not feasible to clean the bearing thoroughly.
- Wipe out maximum amount of earlier grease from the bearing with the help of a cloth ( do not use cotton waste as its threads if struck inside , can lead to failure ).
- Turn the bearing and repeat the wiping out process.
- Spray some cleaning / degreasing agent apply some solvent like CTC , kerosene etc. to melt out the grease
- Again keep wiping after turning the bearing . Keep still for some time allowing the excess solvent to evaporate .
- If possible , blow the compressed air to drive out / blow out remains from the bearing .
- Apply little SG 460 grease in the bearing .
- Box up and pump SG 460 grease through a grease gun.( please use a clean gun)
- Much of the old grease will come out . Wipe off.
- Turn the bearing for say 5 minutes and pump grease by the grease gun .
- This will again force out the old grease . Repeat this last procedure / step a few times .
- Keep a watch on the bearing for any abnormal sound for a day or two
- Normally synthetic grease SG 460 have to be filled 75% to 80% of the bearingcapacity , particularly when bearing ID is 3” or more and RPM is 2500 or more. ( max. 3000 ) . This is a time tested and practical way which we have successfully tried out in many applications where cleaning of the bearing thoroughly is not possible due to some constraints .However , it is always recommended to use clean bearing EVEN NEW BEARINGS HAVE TO BE CLEANED OF ITS ANTI – RUST LAYER
